yTO ALL WHOM IT MAY CONCERN:

Be it linownvthat I, CHARLES N. FARNAM, of Norwich, in the county of New London', and State ot' Conneeticut, have invented a new and useful Machine for Raising and Transferring Hides and Skins While in Process vof Tanning; and I do hereby declare the following to be a full,.elear, and exact description of the same, reference being had to the accompanying drawings, which aro made a part of this specification.

The object of this invention is to facilitate the process of tanning, by so arranging a frame that the hidesV or skins can be attached thereto, and raised from or lowered into the liquor in the'vats collectively and simultaneously; also by the use of a railway-track, toftransfer the hides or skins from. one vat to another, however distant. lIn the drawings- I Figure 1 is a perspective view of my invention.

Figure 2 is a longitudinal section of the same.

Figure 3 is an end elevation of the same.

A A A'A are posts, on which are'mounted horizontal beams B B', forming elevated ,ways extending over and between-the different vats,3into which it is desired to place the hides during different stages of the tanning process.and, if desired, from thence to a suitableplace for dryingor stowing away. On topof these ways are securedrails` C C', on which the frame D runs, its supporting-wheels or rollers O being grooved to' corre.. spend withthe rails. Mounted in bearings cl d', on thc frame D,isa shaft,.K, having keyed to it, at proper points, drums N N'and a gear-wheel, It, which meshes with a pinion, P, on the driving-shaft, which is rotated bya'windlass, M5 or other suitable device, the drivingshaft being also provided with a ratchet-wheel, p, which is enoaved b the awl o', for the ,ur ose of holdin'fr the shaft from retur'ninfrwhcn the rameattached to it is a c y P l F p c a.,

elevated.. The bearings for the driving-shaft aro formed bya downward extension of'tlie outer end of the bear Ving d', which extends down a suicient distance outside of the way A' B' to bring the windlassv M within easy reach ot'l the operator. F F F' F' are ropes, attached at one end-fo thel druins'N` N', and which, after passing over sheaves Elon the outer edges ofthe fr ameD, areattached at their other ends byhooks and staples orother suitable devices to the frame G. This'framc is lof similar form to thevat H, and its sides rest on thev edges vof said vat, when the hides are iu the tan, its ends I and removable cross-bars I' extending into the, liquor in the vat.- On the inner sides of said ends, and on the Tower edges of said barsfare hooks JJ', from which tbehides are suspended. i Y I By turning the windlass M,'the drums N N' are rotated, the ropes 'F F' wound on them, and the frame G I I', with the hides attached to it, is raised from the vat, when thehidcs may be` insp'eeted'and replaced, or remi-ved' to any desired piace, by propclling'the frame D, from' which the frame G is suspended, along the track C C'.

I am aware that a tanning-apparatus has before been used, in which the frame eontainingthe hides is raised and lowered by a windlass, mounted in a carriage running on railsfor transferring the'hides from place to place. This invention, therefore, I do not claim. l

Having thus described my invention, what I claim as new therein, and desire to secure by LcttersPatent, is

1. The windingof the ropcsFF'on drums NN', one side ,winding overand the opposite side winding under the drums, thereby-raising both sides of the frame G equally, substantially as shown and described.

2. Arranging the shaft, to which the motive-power is applied, by the combination of wheelLand pinicnuP7 having aratchet, p, and pawl p', worked by a windlass, M, all arranged so as to pass the posts, thereby avoiding 'interference in transition from'vat to vat, :ts/specified. V n

3.- Th'eeonstruction of the frame G I'Ihaving a shoulder to resten sides of vat, with lower edge of ends Iand movable bars'I' of the frame immersed in the liquor in vthe vat, .when the'frame is down, substantially as shown.l

. 4. Also the two forms of hooks J J", one for ends of frame and one for movable bars, keeping the hides or s'lcins at a suitable-distance from cach other,'so that they will increase in thickness on exposure to thc air when raised, and during the process oftanning; also allowing the hides or skins tev drain when raised from the vats,

thereby facilitating absorption, substantially as vherein describedl` and for the pui-pose specified.
